About 0M904ZX

0M904ZX is the ICD-10-PCS code for a drainage procedure on the head and neck bursa and ligament using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of joint structure, other specified sites and other diagnostic procedures on muscle, tendon, fascia, and bursa, including that of hand, the ICD-9-CM procedure titles it maps to (80.39 and 83.29).

For a different body part, codes include 0M914ZX (right shoulder bursa and ligament), 0M924ZX (left shoulder bursa and ligament), 0M934ZX (right elbow bursa and ligament), 0M944ZX (left elbow bursa and ligament), 0M954ZX (right wrist bursa and ligament), 0M964ZX (left wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0M900ZX (open) and 0M903ZX (percutaneous).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
